Question 161: Motion in 2D & Vectors

Question

A bullet is fired from a gun at the speed of $$280 \mathrm{~ms}^{-1}$$ in the direction $$30^{\circ}$$ above the horizontal. The maximum height attained by the bullet is
$$\left(g=9.8 \mathrm{~ms}^{-2}, \sin 30^{\circ}=0.5\right)$$:-

Accepted Answer

$$\mathrm{H}_{\max }=\frac{\mathrm{u}^{2} \sin ^{2} 	heta}{2 g}$$
$$
=\frac{(280)^{2}\left(\sin 30^{\circ}ight)^{2}}{2(9.8)}
$$
$$=1000 \mathrm{~m}$$

Answer

2000 m

Answer

1000 m

Answer

3000 m

Answer

2800 m
